Patented Mar. 17, 1931 UNITED STATES PATENT OFFICE CLARENCE WEIGHT, 0] BACINE, WISCONSIN, ASSIGNOB TO WRIGHT RUBBER PRODUCTS COMPANY, OF BACINE, WISCONSIN, A CORPORATION OF WISCONSIN PAVING BLOCK Application filed November 12, 1924, Serial No. 749,450. Renewed March 3, 1 930.

paving block which will be strong and durable.

having flanges which are firm and strong.

The block is ordinarily made of resilient substance, for instance, rubber or other suitable material, and molded or pressed into shape.

According to the invention, the flanges of the block have reinforcements of cloth or wire fabric or other suitable substance a plied thereto or embedded therein to ma e them strong and firm.

The block is used for paving roads streets and walks, covering floors and wails, and various other purposes.

It is particularly suitable for pavements for vehicles as it is very durable and will stand heavy strains.

Blocks embodying the invention are shown in the accompanying drawings in which the views are as follows:

Fig. 1 is a bottom plan view of a block having a reinforcement substantially coextensive with the base thereof.

Fig. 2 is a plan of the reinforcement shown in Fig. 1. 9

Fig. 3 is a longitudinal section through the block shown in Fig. 1.

Fig. 4 is a bottom plan view of a block having reinforcing strips applied to the base thereof.

Fig. 5 is a plan of a reinforcing strip.

Fig. 6 is a bottom plan view of a block having another form of reinforcement applied to the base thereof.

Figs. 7 and 8 are plan views of the reinforcements shown in Fig. 6.

The invention is shown embodied in a paving block of the form disclosed in the patent to Healy, Reissue No. 16,867 of February 7, 1928, but it may also be incorporated in other forms of paving blocks.

Another object is to provide a paving block The block has a top 1 of rectangular or other suitable shape and a bottom which is EI'OVldGCl with flanges 2 projecting from the lock and recesses 3 underneath the top.

These flanges and recesses correspond in shape and size and are arranged contiguously or side by side with the edges thereof merging into each other.

The top and bottom have vertical edges and the flanges and recesses have flat tops.

The flanges have embedded therein, or otherwise applied thereto, a reinforcement of cloth or wire fabric or other suitable substance to make them firm and strong so that they will stand the strain and stress imposed thereon.

The reinforcement extends from the flange into the body of the block. I

The block shown in Fi s. 1 and 3 has a reinforcement 4 which is su stantially coextensive with and of the same configuration as the bottom of the block.

The block shown in Fig. 4 has a reinforcement of diagonal strips 5 united to the bottom thereof and reinforcing the flanges 2 on the sides of the block.

The block shown in Fig. 6 has a reinforcement of discs 6 and 7 united to the bottom thereof and reinforcing the flanges 2.

The flanges are provided with flat tops and accordingly they will positively interlock the block vertically in alinement with its adjoining blocks and not tend to separate the block from the adjoining blocks, and accordingly they are adapted to have nails or other fastening means passed therethrough to hold the block in place.

When blocks such as have been disclosed are in a pavement or other covering and adjoin each other, they are mutually interlocked by the flanges and thereby kept from relative vertical and sidewise displacement.

The flanges on each block are overlapped by the adjoining blocks and set in the recesses thereof.

The blocks may be fastened to their support or foundation by nails or other means passing through holes in'the flanges thereof, and thereby kept from warping and creeping.

In addition to strengthening and stiffening vertical edges and shaped to form entirely around said block alternate flat top flanges and recesses to interlock said block vertically and laterally in both directions to its adjoining blocks, and means applied to said flanges and said bottom to reinforce and strengthen said flanges.
